drivers: of/base: move of_init to driver_init
Commit 5590f3196b29 ("drivers/core/of: Add symlink to device-tree from devices with an OF node") adds the symlink `of_node` for each device pointing to it's device tree node while creating/initialising it. However the devicetree sysfs is created and setup in of_init which is executed at core_initcall level. For all the devices created before of_init, the following error is thrown: "Error -2(-ENOENT) creating of_node link" Like many other components in driver model, initialize the sysfs support for OF/devicetree from driver_init so that it's ready before any devices are created.
